RESUMEN
Background and objective The coronavirus disease 2019 (COVID-19) pandemic, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), presents multiple, diverse challenges to providing appropriate medical care, especially in terms of medication and treatment adherence for chronic diseases such as type 2 diabetes mellitus (T2DM). The COVID-19 pandemic has exacerbated these barriers by potentially forcing physicians to modify their treatment plans due to limitations on in-person visits and changes to patients' financial and social support systems. It remains uncertain whether physicians believe they can provide the same standard of care using telehealth technology or other means to their patients during the pandemic. The goal of this study was to explore physician perceptions about their ability to provide care to patients with T2DM during the COVID-19 pandemic. Methodology This cross-sectional study collected data between January 25, 2021, and February 2, 2021, using an anonymous, self-administered online survey involving DO and MD physicians including residents treating patients with T2DM. The survey was administered via REDCap and collected data on participant demographics, attitudes, perceptions, knowledge, and prior and current (COVID-19-era) experience with care for T2DM patients. Physicians registered with the Florida Department of Health with publicly available emails were invited to participate. Results The survey showed that during the COVID-19 pandemic, 57.9% of physicians (n=48) believed that their patients have a weaker social support system; 68.7% (n=57) modified their patient care plans due to patients' financial difficulties; 78.4% (n=65) believed a regular physical exam is necessary to properly treat patients; 48.2% (n=40) did not believe they had a more complete picture of the case with remote consultations; 47.0% (n=39) were not as satisfied with remote consultations as with face-to-face patient visits; 68.7% (n=57) believed telehealth is necessary to adequately treat patients; 38.5% (n=32) have been less likely to refer their patients to other providers or specialists; 45.8% (n=38) reported concerns over admitting their patients to the hospital for acute medical care; 61.5% (n=51) reported having more patients delay scheduling their routine follow-up care; 61.5% (n=51) believed their patients have been less compliant with the healthcare plans recommended to them. Conclusions The study showed that COVID-19 has significantly impacted physicians' perceptions and abilities to provide care for patients with T2DM. COVID-19 has negatively impacted several crucial aspects of diabetes management, including consistent in-person examinations, social support, and referral to other required services, which could result in long-term consequences for these patients. Furthermore, our study suggests that physicians may not be as satisfied with the care they are able to provide via remote consultations as they are with in-person visits, which has significant implications as we move toward a more telehealth-driven healthcare delivery system.
RESUMEN
In this study, we perform a region of interest diffusion tensor imaging and advanced diffusion complexity analysis of normal appearing white matter to determine the impact of vascular health on these diffusivity metrics in midlife adults. 77 participants (26 black, 35 female) at year 30 visit in the Coronary Artery Risk Development in Young Adults longitudinal study were scanned with an advanced diffusion-weighted imaging and fluid-attenuated inversion recovery protocol. Fractional anisotropy and non-linear diffusion complexity measures were estimated. Cumulative measures across 30 years (9 study visits) of systolic blood pressure, body mass index, glucose, smoking and cholesterol were calculated as the area under the curve from baseline up to year 30 examination. Partial correlation analyses assessed the association between cumulative vascular health measures and normal appearing white matter diffusion metrics in these participants. Midlife normal appearing white matter diffusion properties were significantly associated (P < 0.05) with cumulative exposure to vascular risk factors from young adulthood over the 30-year time period. Higher cumulative systolic blood pressure exposure was associated with increased complexity and decreased fractional anisotropy. Higher cumulative body mass index exposure was associated with decreased fractional anisotropy. Additionally, in the normal appearing white matter of black participants (P < 0.05), who exhibited a higher cumulative vascular risk exposure, fractional anisotropy was lower and complexity was higher in comparison to normal appearing white matter in white participants. Higher burden of vascular risk factor exposure from young adulthood to midlife is associated with changes in the diffusion properties of normal appearing white matter in midlife. These changes which may reflect axonal disruption, increased inflammation and/or increased glial proliferation, were primarily observed in both anterior and posterior normal appearing white matter regions of the corpus callosum. These results suggest that microstructural changes in normal appearing white matter are sensitive to vascular health during young adulthood and are possibly therapeutic targets in interventions focused on preserving white matter health across life.
RESUMEN
High blood pressure (BP) negatively affects brain structure and function. Hypertension is associated with white matter hyperintensities, cognitive and mobility impairment in late-life. However, the impact of BP exposure from young adulthood on brain structure and function in mid-life is unclear. Identifying early brain structural changes associated with BP exposure, before clinical onset of cognitive dysfunction and mobility impairment, is essential for understanding mechanisms and developing interventions. We examined the effect of cumulative BP exposure from young adulthood on brain structure in a substudy of 144 (61 female) individuals from the CARDIA (Coronary Artery Risk Development in Young Adults) study. At year 30 (Y30, ninth visit), participants (56±4 years old) completed brain magnetic resonance imaging and gait measures (pace, rhythm, and postural control). Cumulative systolic and diastolic BP (cumulative systolic blood pressure, cDBP) over 9 visits were calculated, multiplying mean values between 2 consecutive visits by years between visits. Surface-based analysis of basal ganglia and thalamus was achieved using FreeSurfer-initiated Large Deformation Diffeomorphic Metric Mapping. Morphometric changes were regressed onto cumulative BP to localize regions of shape variation. Y30 white matter hyperintensity volumes were small and positively correlated with cumulative BP but not gait. Negative morphometric associations with cumulative systolic blood pressure were seen in the caudate, putamen, nucleus accumbens, pallidum, and thalamus. A concave right medial putamen shape mediated the relationship between cumulative systolic blood pressure and stride width. Basal ganglia and thalamic morphometric changes, rather than volumes, may be earlier manifestation of gray matter structural signatures of BP exposure that impact midlife gait.

BACKGROUND: High blood pressure (BP) is a known risk factor for mobility and cognitive impairment in older adults. This study tested the association of cumulative BP exposure from young adulthood to midlife with gait and cognitive function in midlife. Furthermore, we tested whether these associations were modified by cerebral white matter hyperintensity (WMH) burden. METHODS: We included 191 participants from the CARDIA study (Coronary Artery Risk Development in Young Adults), a community-based cohort of young individuals followed over 30 years. Cumulative BP was calculated as the area under the curve (mm Hg×years) from baseline up to year 30 examination. Gait and cognition were assessed at the year 30 examination. Cerebral WMH was available at year 30 in a subset of participants (n=144) who underwent magnetic resonance imaging. Multiple linear regression models were used to assess the association of cumulative BP exposure with gait and cognition. To test effect modification by WMH burden, participants were stratified at the median of WMH and tested for interaction. RESULTS: Higher cumulative systolic and diastolic BPs were associated with slower walking speed (both P=0.010), smaller step length (P=0.011 and 0.005, respectively), and higher gait variability (P=0.018 and 0.001, respectively). Higher cumulative systolic BP was associated with lower cognitive performance in the executive (P=0.021), memory (P=0.015), and global domains (P=0.010), and higher cumulative diastolic BP was associated with lower cognitive performance in the memory domain (P=0.012). All associations were independent of socio-demographics and vascular risk factors (body mass index, smoking, diabetes mellitus and total cholesterol). The association between cumulative BP and gait was moderated by WMH burden (interaction P<0.05). However, the relation between cumulative BP and cognitive function was not different based on the WMH burden (interaction P>0.05). CONCLUSIONS: Exposure to higher BP levels from young to midlife is associated with worse gait and cognitive performance in midlife. Furthermore, WMH moderates the association of cumulative BP exposure with gait, but not with cognitive function in midlife. The mechanisms underpinning the impact of BP exposure on brain structure and function must be investigated in longitudinal studies using a life course approach.

OBJECTIVES: There is limited research on the attitudes of pharmacy technicians toward pharmacy naloxone provision, despite their widespread role in the pharmacy. We examined attitudes and perceptions of pharmacy technicians in the provision of naloxone in a sample of Massachusetts pharmacies. DESIGN: Thirty-nine community retail pharmacies from 1 U.S. chain were purposely sampled in 13 municipalities across Massachusetts. Pharmacies were divided into high-risk municipalities (HRMs) versus low-risk municipalities (LRMs) based on the state average opioid-related death rate from 2011 to 2015. SETTING AND PARTICIPANTS: A pharmacy technician working in each pharmacy was administered an in-person survey. Survey topics included technician beliefs about current naloxone provision practices; patient groups at greater risk of overdose; whether individuals filling prescriptions would benefit from naloxone; and whether individuals purchasing syringes would benefit from naloxone. OUTCOME MEASURES: Closed-ended responses were analyzed by Mann-Whitney U, Fisher exact, and chi-square tests. Open-ended responses were summarized for themes and then contrasted by municipality risk status. RESULTS: Technician participation was 100% (n = 39). Technicians in both groups believed they could identify patient groups at risk of overdose in their practice, but HRM technicians recognized the need for naloxone for more of their at-risk patients (81% in HRM vs. 33% in LRM believed > 25% of patients need naloxone, P < 0.01). A willingness to provide naloxone was high (> 89%) in both groups. Open-ended responses revealed commonalities between groups, including the belief that patients need lower-cost naloxone, and a lack of patient and technician awareness that naloxone could prevent overdose in individuals at risk through use of prescription opioids not just through use of illicit drugs. CONCLUSION: Pharmacy technicians would benefit from overdose prevention training and are well positioned to recognize overdose risk and offer preventive interventions, such as naloxone. Among technicians, there is a high willingness to be involved in implementing broader naloxone access in pharmacies.
